HORN
Piezoelectric Horn Driver, and Comparator
Piezoelectric Horn Driver, Feedback. This input is connected to the feedback electrode of the horn. If FEED is
not used, it should be grounded.
Piezoelectric Horn Driver, Horn Brass. This output pin is connected to the piezo metal support electrode of the
horn.
Piezoelectric Horn Driver, Ground. This pin should be connected to GND, the same ground as pin 1. There is
no special isolation required for this pin.
Piezoelectric Horn Driver, Horn Silver. This output pin is connected to the ceramic electrode and provides the
complementary output to HORNB when the horn output is enabled.
Digital Power. This pin should be connected to a bypass capacitor to ground.
Voltage Regulator Output. This pin provides the regulated output of the internal voltage regulator. This pin
requires sufficient bypass capacitance, preferrably a parallel combination of 10µF and 0.1µF capacitors
between this pin and ground.

Active-Low Reset Input or General-Purpose, Digital I/O, Type D Port. This pin defaults to the reset input
mode of operation following a POR. The reset input mode can be deactivated and the digital I/O mode enabled
by programming the RSTD bit to 1.

High-Current (Sink) Driver Output or General-Purpose, Digital I/O, Type D Port. This pin functions with a
high-current pulldown to drive a device such as an LED or as a bidirectional I/O. The pin defaults to a digital
input with a weak pullup after a reset.
External Edge-Selectable Interrupt or General-Purpose, Digital I/O, Type D Port. This pin functions as either
an external edge-selectable interrupt or as a bidirectional I/O. The pin defaults to a digital input with a weak
pullup after a reset.
Analog Voltage Comparator Input or General-Purpose, Digital I/O, Type D Port. This pin functions as either
the input to the analog voltage comparator or as a bidirectional I/O. The pin defaults to a digital input with a weak
pullup after a reset.
